One side effect of using your smartphone, tablet, or computer is exposure to artificial blue light, which has been linked to negative impacts on eye health, sleep quality, and overall well-being. Blue light emissions from the display screens of digital devices may cause eye strain, which can lead to fatigue, headaches, and blurry vision.
Blue light exposure may also suppress the production of melatonin, a hormone that controls your sleep patterns. This can lead to fatigue, insomnia, and disrupted sleep patterns, especially if you use your device in the evening and at night.
Fortunately, there are several types of blue-light-filtering products that you can use to limit your exposure. Blue light screen protectors block blue light from electronic devices such as phones, tablets, or computers.
Read on to take a look at our list of some of the best blue light screen protectors. You’ll also learn more about the effectiveness of blue light screen protectors and what to look for when purchasing one.

Before you buy a blue light screen protector, consider the following:
- Company reputation. Look for a reputable company that backs product quality with a generous warranty or return policy. Read online customer reviews and ratings from Trustpilot or the Better Business Bureau (BBB). Check out the company’s website to get a feel for the brand.
- Product quality and effectiveness. Look for companies that use third-party testing and certification. Choose brands that are designed or recommended by healthcare professionals.
- Visual quality. To prevent distortion and discoloration, select a screen protector that retains the display’s original color and brightness.
- Size. Make sure the dimensions of the screen filter are the correct size for your device. Most brands offer filters to fit specific models.
- Additional features. Some filters will also include coatings that protect your screen from impacts, scratches, and smudges. Privacy and anti-glare filters are also available.
- Eyewear. You can wear prescription and nonprescription eyeglasses when you’re using electronics. Some eyewear can include blue light or glare reduction in the lenses for prolonged screen time.
- Night mode. You can use the night or dark mode feature built into your device.
- 20-20-20 exercise. Many eye doctors also suggest practicing the 20-20-20 rule. After about 20 minutes of looking at a screen, look at something at least 20 feet away for 20 seconds. No matter how far away or near you let your gaze go, the main goal is to look away from the screen and let your eyes take in other objects and distances to reduce strain and fatigue.
- Lightbulbs. If you feel screens are impacting your sleep, you can use blue-light-blocking lightbulbs, especially in the rooms where you spend the most time at night.
- Less screen time at night. When possible, limit your screen time, especially after sunset. Design a nighttime routine that will help you to wind down in the evening, so you can fall asleep more easily, experience deeper sleep, and wake up feeling energized.
Blue light from electronic devices may impact your sleep, vision, and overall well-being. For those times when you must be on your mobile phone, tablet, or computer, screen protectors and other options can reduce the impact.
